Model Arena — Compare, Cost, and Crash-Test Open-Source LLMs on Crusoe Managed AI

A HuggingFace Spaces app that lets developers:
1. Compare open-source models head-to-head (Arena)
2. See real cost economics vs proprietary APIs (Cost)
3. Simulate endpoint outages and watch failover in action (Resilience)

All inference powered by Crusoe Managed AI.
